Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is tough to deal with in a standard mill.
เกจวัดแรงดันปั๊มลมpuma is a disc agitator bead mill modified for coarse grinding with high throughput and a grinding chamber quantity of approx. 20 litres. In the peripheral velocity range of 8–12 m/s, a product throughput of as a lot as 25 m³/h may be achieved with this machine measurement. เกจวัดอาร์กอน of the grinding media used sometimes ranges from 2.zero –4.zero mm.
During improvement of the pre-grinding unit, a disc agitator was chosen as a result of the identical web power input yields virtually double the grinding chamber volume than when utilizing a pin agitator. This gives considerably extra grinding physique contacts and a bigger cooling surface for grinding.
With a pre-grinding unit, the particle measurement distribution of a product may be adjusted in order that very small grinding media can be used in the subsequent fine-grinding stage. Tests have proven that course of control with the Netzsch PROPHI pre-grinding unit can scale back the particular vitality requirement by more than 50% as in contrast with using classic pre-dispersion methods.
